The Interactive NGC Catalog Online

This is the interactive NGC (and IC, and Messier) catalog at
SEDS, based on the famous
NGC 2000.0 by R.W. Sinnott of Sky Publishing Corp., who also created the
electronic version used by this online service (thanks to
Sky Publishing for permitting us this
kind of use).
Only some minor corrections have been included
in our online database.
The HTML interface and its features were created by
Hartmut Frommert.
Thanks to Bill Arnett
for helpful hints and support, and the admins of
SEDS who provided the appropriate
hardware and software basis for this service.
Thanks to Bernard Trézéguet, this service is now available in
French language also.

The NGC and its supplements IC I and IC II were originally compiled by
J.L.E. Dreyer and published 1887 (NGC), 1895 (IC I) and 1908 (IC II).
It contains open and globular star clusters (and some asterisms), diffuse
and planetary nebulae, supernova remnants, galaxies of all types (and some
knots in bright galaxies), and some erroneous entries corresponding to
single or double stars, or no objects at all.

You will get the NGC 2000.0 data for each NGC, IC, or Messier object,
including J.L.E. Dreyer's description code. Moreover,
for most of the objects, cross identifications
are given for some (mostly older) catalogs, including John Herschel's GC
of 1864 (with Dreyer's later extension), John Herschel's 1833 and 1847
catalogs ("h"), William Herschel's catalog published between 1786 and 1802
("H"), Lacaille's catalog of 1755 ("Lac") and James Dunlop's catalog of
1828 ("Dun"), as well as the sources and references given in Dreyer's
original catalog, and some collected remarks.

Please type in the NGC number (either as number only, or preceded by 'NGC'
or 'N'), or the IC number preceded by 'IC' or 'I', or the Messier number
preceded by 'M', of the object you'd like to find.
Some browsers (e.g., Lynx) require that you hit a key ('s' or 'S' for Lynx)
to activate the input line.

Note: (as of February 2002; still necessary in 2012)
Some versions of some browsers are unable to handle our interface correctly.
In this case, use the following entry, and then the input line
there for your inquiry: NGC 1.

Statistics:

As of the counting of July 2007, we have the following statistics for the
Messier, NGC, and IC catalog:

The NGC/IC Project maintains an
online database of various versions of the NGC and IC catalogs and
related material, including an interactive observing list generator.
Note in particular the scanned online versions of the
NGC
and IC
catalogs.
